l'Clalniu (c1. Isle-203) This invention relates to pipes for smokingtobacco, and in particulara pipe having a bowl which is so constructedthat moist products of combustion containing nicotine and otherprodeucts that normally settle in the lower partof the bowl, pass through asmall opening in the center of the bottom of the bowl and into acartridge of absorbent material in a perforated cylindrical containerpositioned in a pocket below the bowl.

The purpose of this invention is to provide means in a smoking pipe forabsorbing objectionable products such as moist products resulting fromburning tobacco whereby smoke free from objectionable matter is drawnthrough the pipe stem into the mouth of the smoker The object of thisinvention is, therefore, to provide means for incorporating a cartridgeof absorbent material in the lower part of a pipe so that moist productsof combustion resulting from burning tobacco in the pipe pass downwardlyby gravity into the cartridge.

Another object of the invention is to provide a pipe having in a pocketunder the bowl a cartridge of absorbent material which will absorb thenicotine and effectively prevent it from flowing through the stem andmouthpiece of the pipe to the mouth of the person smoking the pipe.

Another object of the invention is to provide a pipe of this characterwherein a cartridge of absorbent material is placed in a cylindricalcontainer which is thrust into place through the open rear end of thepocket under the bowl of the pipe.

Another object of the invention is to so form the container that it maybe easily opened for removal of a cartridge and insertion of a newcartridge.

Another object of the invention is to provide a pipe which is clean,cool smoking and very simple in construction.

The invention is illustrated in the accompanying drawing wherein:

Figure 1 is a sectional view taken longitudinally through a pipe of theimproved construction;

Figure 2 is a view taken along the line 2-2 of Figure 1;

Figure 3 is a view showing the pipe in section taken on line 3-3 ofFigure 2, with the strainer in elevation;

Figure 4. is a view taken along the line 4-4 of Figure 3 Figure 5 is aperspective view looking at the outer end of the filter or strainer, aportion being shown in section;

Figure 6 is a view similar to Figure 5 looking at the inner end of thefilter.

Figure 7 "is aside view-showing the :containerof the filter openedforremoval or insertion otna cartridge.

=' The improved pipe of this invention is: formed with a body having a'bowl I from which .a stem 2 extend-sand the stem is provided with asocket 3 ior receiving the small. end portion 4 vor a mouthpiece or tip5. The stem is providedwith a reinforcing sleeve 6 and the bore 1 of thestem is positioned in registering relation with the bore 8 of themouthpiece.

The lower part of the bowl and the adjoining part of the stem areprovided with an enlarged portion I 0 which is provided with alongitudinally disposed bore providing a pocket I l the outer end ofwhich is open. The lower part of the bowl is provided with an opening I2that provides communication between the bowl and pocket. The inner endof the bore or pocket II is connected with the bore of the stem througha passage I31 which is inclined upwardly from the pocket II.

With the parts arranged in this manner the gases of combustion are drawndirectly through the stem and mouthpiece and the moist products ofcombustion pass downwardly by gravity through the opening I2 and into astrainer consisting of a cartridge I5 of absorbent material which ispositioned in a perforated cylindrical container I4 in the pocket II, asdescribed more fully below. Filtered gases may pass from the pocket andcartridge therein through the passage I3 into the stem and mouthpiece- Astrainer is removably mounted in the pocket and consists of a containerin which is a cartridge I5 formed of absorbent material. The containeris formed of thin metal and of cylindrical shape, the container beingsplit longitudinally to provide a section I6 which is pivotally mountedby a pin I! on the main section I4 and when closed has edge to edgeengagement with the main section of the container so that they coopcratewith each other to form a cylindrical container having its open outer orrear end closed by a head or plug I8 carried by the main section I4, theneck I9 of which fits snugly into the front end of the pocket II. Aftera cartridge I5 has been fitted into the container the section I 6 ismoved to the closed position and the head I8 is then grasped and thecontainer inserted into the pocket to the position shown in Figures 1and 3.

When the pipe is smoked, the moist products of combustion will passdownwardly through the opening and will be absorbed by the cartridge I5.Also any undesirable matter including saliva that may be in the smokepassage 8 may flow down the inclined passage I3 to be absorbed by thecartridge. When the cartridge has absorbed as much as it will hold thehead I8 is grasped and the container withdrawn from the pocket. Thesection It is then swung to the opened position shown in Figure 7, thecartridge removed, and a new cartridge fitted into the container. Thesection It is then returned to the closed position and the strainerthrust back into the pocket.

Having 'thus described the invention, what is claimed is:

In a smoking pipe, prises a pipe body including a extended at one sideand having a remova tip carried by the stem, a passage adjacent side ofthe bowl at said stem and tip having therethrough communicating with thethe inner endofthe I the combination which com:

bowl with a stem ble passage, said body having a downwardly extendeddepending section with a cylindrical bore therein I parallel to thepassage of the stem and tip and spaced therefrom, said body havingan-oriflce in the lower end of the bowl communicating; with the bore inthe said extended depending section, said depending section having aninclined opening at the inner end thereof providing communicating meansbetween the bore of the depending section and the passage of the stem; aperforated cylindrical container formed of two hinged secbore.
